WFC has prepared a detailed engineering report for the CC Company and has been diligently <br />working with them on the final approval of the relocation and restoration. Although CC Company <br />is in overall agreement of the plan, final approval has not yet been achieved. Once this <br />documentation is available, it will be supplied to the Division. <br />Design Details <br />1) The pipeline will be a continuous fused polyethylene pipe of 28 inch outside diameter with <br />no joints that will roll with the terrain. This pipe is the best choice for tough applications and long <br />term durability. <br />2) The pipe wall thickness of 1.33 inches is resistant to weather and wear and will remain <br />flexible. The polyethylene material is made to last indefinitely. <br />3) Other specifications: 80 psi rating (more than adequate), inside diameter 25.33 inches, <br />length of approximately 4000 feet. <br />4) The pipe has excellent flow characteristics and will handle 25 cfs during the 6 years of <br />temporary installation and will pass 38 cfs for the permanent location. All takeoffs for irrigation in <br />• the permanent line will be based on a main pipe flow of 38 cfs. <br />5) Each takeoff will have a valve and weir for control and measurement of the outflow. <br />6) The pipe is extremely durable and will avoid many pitfalls of other pipe types. See Section <br />13 for a detailed discussion of the longevity and maintenance items. <br />7) The temporary pipe will be laid on the surface while the permanent pipe will be buried. The <br />permanent line will not interfere with any post-reclamation land uses. <br />8) A pressure regulator will be placed in the line near the exit to control flow in the entire <br />pipe. <br />9) During the temporary pipe time frame, the Reeder/Garret/Johnson distribution box will be <br />supplied from an 8" diameter SDR 26 pipe leading from the main pipe. <br />Timin <br />1) Temporary pipe will be laid during sometime in 2001 and will be put into operation either <br />during for the latter part of the irrigation season of 2001 or will be ready for the 2002 season. This <br />will depend on mining advance. <br />(Revised 12/00) Attachment 2.05.3(3) -10-103 <br />
